It'd need lots of changes. CMake generally uses absolute paths to the
source tree and sometimes to the build tree (I forget the cases where it
does, but that is somewhat generator-dependent). At least one is for the
Makefiles generator where it embed absolute paths in its `cd` commands
before running the compiler. It would likely not be trivial to get CMake
to generate relocatable builds.
